Made from Grade 5 steel, these locknuts are suitable for fastening most machinery and equipment.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel.

Made from low-strength steel, these locknuts should be used for light duty fastening applications, such as securing.access panels.

These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.

Choose these locknuts for their adherence to strict military standards for material and construction.

Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.

Use these locknuts for light duty fastening applications, such as securing access panels.

Grade F nuts are comparable in strength to Grade 5 bolts.

Grade G nuts are comparable in strength to Grade 8 bolts.

A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris.
